So, now I came up with an idea of making it more like 150 pages with a casual conversation style of writing, and divide it into 3 parts, and make it audio lectures, then Sell it as 3 sets of CDs (Mp3), and add an ebook as a bonus (complete transcript). Then I probably don't need much more bonus products (probably I will come up with 1 or 2 bonud products)
Do you think it is a good idea?
I was actually thinking about audio lectures as my back-end product (more than 3 CDs and expensive) so I'm not sure if I should "use up" an idea of backend product at this point.
Is it better to sell just an e-book with a cheaper price and make back-end product expensive with more sets of audio cds? What do you guys think?
